Remove WARN log lines for authentication failures

[hjacobs]

Should not spam the log with WARNINGS about client's missing permissions. I propose changing these log lines to "INFO" and delete some places (e.g. if no auth was given).

This issue is about having clean logs. Internet-facing services will always get random requests without authentication --- this should not lead to WARNINGs in the logs as it does not trigger any action (developers will see WARNINGs but can't do anything about it as you cannot "control the internet" to avoid "random" requests from spiders etc).

WARNINGs should always be "actionable", i.e. I should be able to fix them as a developer.

@LappleApple why did you close this?

1. It's written like a ticket for our use only; 2. nobody's touched it for +1 year.

[hjacobs]

@LappleApple I still think the change makes sense (has nothing to do with our internal use) and I would leave this for the maintainers to decide.. :smirk:

@hjacobs Noted. I removed your "we"

@LappleApple as some background information: this issue is about having clean logs, internet-facing services will always get random requests without authentication --- this should not lead to WARNINGs in the logs as it does not trigger any action (developers will see WARNINGs but can't do anything about it as you cannot "control the internet" to avoid "random" requests from spiders etc).

Thanks, @hjacobs: I've added it to your initial comment because it's nice context for anyone who stumbles across this issue and doesn't enjoy scrolling. :)

Tagging the issue with "help wanted" as it shouldn't be hard and might thus be a nice way for new contributors to get started with the project.
